我国研究人员在新一期《自然·遗传学》杂志上发表报告说,他们找到了一个可同时提高水稻产量和品质的基因,未来可将其应用到超级杂交水稻新品种培育中。报告称,长期以来中国水稻育种的主要目的是保证产量提升,而高产水稻品质有时较差,如何解决“高产不优质,优质不高产”问题一直是水稻育种面临的难题。中国科学院遗传与发育生物学研究所傅向东研究员带领的团队从优质水稻不育系“泰丰a”中成功分离并克隆了一个控制水稻粒形和提升稻 In a report in the journal Nature Genetics, our researchers report that they have found a gene that can simultaneously increase the yield and quality of rice, which can be applied to the cultivation of new hybrid rice varieties in the future. The report said that the main purpose of rice breeding in China for a long time is to ensure that the output is increased while the quality of high-yielding rice is sometimes poor. How to solve it? The problem of “high-yielding and low-quality, high-quality and low-yielding” has always been a challenge for rice breeding. The team led by researcher Fu Xiangdong from the Institute of Genetics and Developmental Biology, Chinese Academy of Sciences successfully isolated and cloned a rice grain that controlled grain shape and raised rice from high quality rice CMS line “Taifeng a”
